Why Are Copper Terminal Blocks More Suitable For Low-current Environments?

The copper terminal block structure uses pure copper or high-purity copper alloy, possessing excellent electrical and thermal conductivity. Copper is one of the common terminal materials because copper distribution block has good conductivity, corrosion resistance and high mechanical strength. In low-current environments, a stable conductive path reduces contact resistance, which is crucial for the accurate transmission of control signals.

From a connection reliability perspective, the copper terminal strip can maintain low power consumption and low temperature rise in low-current scenarios, which helps extend component life. For low-current circuits, the current density is low, and the low resistance of copper reduces unnecessary heat accumulation.
